The magnetic sensor is to convert the magnetic elements of the magnetic element, such as magnetic fields, current, stress response, temperature, light and other external factors. Magnetic performance changes into electrical signals to detect the corresponding physical quantities in this way.Magnetic sensor is divided into three categories: compass, magnetic field sensor, position sensor.
Application of magnetic sensor
Important applications are the reading and writing of magnetic information products.The tapes and disks we used in the last century made a large amount of information entry and record.This is a major leap for the development of my countrys information industry.Meet a large amount of information on information in my country.With the development of the economy and the advent of the Data Big Bang, a large number of magnetic information products have been spawned.Furthermore is the management of energy.The traditional computer systems can not be detected for the detection of the citys power grid and various communication networks, so the sensor uses current to achieve automatic monitoring and self -control control.The magnetic sensor also contributes to the development of power electronic technology. Its emergence realizes the combination of power technology and electronic technology, thereby realizing direct transformation between currentthe size of.The production of the automotive industry has huge demand.According to statistics, one -third of the motor of a senior vehicle must be used by magnetic sensors. Although the motor is diversified, the magnetic sensor can make corresponding needs for different clicks.
Principles of magnetic sensors
When the signal rotor on the magnetic sensor rotates in the direction of clockwise, the air gap generated between the convex teeth and the magnetic head of the magnetic field on the rotor will also be reduced. ThereforeAs follows, the magnetic flux increases.When the convex teeth of the rotor are about to approach the edge of the magnetic head of the magnetic field, the magnetic flux will rise sharply. At this time, the magnetic flux change rate reaches the maximum, and the induction of the electromotive force also reaches the highest point.However, when the signal rotor rotates to the central line of the convex teeth in clockwise, at this time, the central line of the convex teeth and the center line of the magnetic field of the magnetic field is stacked, although the convex teeth of the signal rotor and the magnetic field of the magnetic field head and the magnetic head of the magnetic fieldThe air gap reaches the minimum value, but the magnetic flux at this time reaches the highest point, but because the magnetic flux is impossible to continue to rise continuously, the change rate of the magnetic flux at this time is equal to 0.
